'Commander' in the Bible

While Peter and John were speaking to the people, the priests and the commander of the temple guard and the Sadducees came up to them,

Now when the commander of the temple guard and the chief priests heard this report, they were greatly puzzled concerning it, wondering what this could be.

Then the commander of the temple guard went with the officers and brought the apostles without the use of force (for they were afraid of being stoned by the people).
